Question

I am trying to make on top some padding but how to do this with Container?

    JFrame frame = super.screen.getFullScreenWindow();
    //Container contentPane = frame.getContentPane();
    //JPanel contentPane = new JPanel();

    // Make sure the content pane is transparent
    if (contentPane instanceof JComponent) {
        ((JComponent)contentPane).setOpaque(false);
    } 
    else {
      // ??
    }

    contentPane.setBorder(new EmptyBorder(10, 10, 10, 10) );
    //frame.getContentPane().add(contentPane, BorderLayout.CENTER);

Output

 [javac] symbol  : method setBorder(javax.swing.border.EmptyBorder)
 [javac] location: class java.awt.Container 
 [javac] contentPane.setBorder(new EmptyBorder(10, 10, 10, 10) );
 [javac]

You can override Container#getInsets, although you should be using Swing components.
